ATTACHMENT FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 489,353, dated January3, 1893. Application filed June 9,1892. snn No. 436,135. (No model.)

To all whom, it may concern.-

Be it known that I, WARREN WEBSTER, a citizen of the United States, anda resident of Oarneiro, in the county of Ellsworth and State of Kansas,have invented certain new and useful Improvements in Attachments forGrain- Drills; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a top plan view. Fig. 2 is a side view andFig. 3 is a sectional detail view on line was, of Fig. 1.

This invention has relation to certain new and useful improvements inseed drill attachments, and consists in the novel construction andcombination of parts, all as hereinafter specified.

In the accompanying drawings, the letter A designates the draw bar ofthe attachment,which is preferably of metal, and forked at its forwardend for attachment to the drill frame (not shown). Said bar is alsoforked at its rear portion, forming arms B, which are curved laterallyand downwardly, and are in turn each forked or bifurcated to form armsa, 0t, and b, I). Usually, as shown, said bar is formed in two pieces,bolted or otherwise suitably secured together, each piece being curvedoutwardlyand downwardly to form the arms B.

D, D, designate rotary disks or colters which are mounted on short axlesd, (1, one of which is journaled between each pair of arms a, a, and b,b, in brackets e, which are adj ustably secured to said arms. The disksor colters D, D, are of dished or concave form, and as their axles d, d,are journaled in oblique position, they occupy a converging positionwith relation to each other, as shown, which avoids side draft. Byvarying the adjustment of the brackets e on the arms, the disks may beset at different angles, as may be necessary or desirable.

F, F, designate the grain spouts, one at each side, and clipped orotherwise suitable secured to the arms a and b. Said spouts at theirlower ends are turned or curved rearwardly, which prevents theirbecoming clogged with dirt, or other obstruction with which they areliable to come in contact. A

cutter G is also secured to each at the lower front portion, whichservesto assist the disks in opening the drills, the lower portions of thespouts lying close to the wheels. By reversin g the clips F which holdthe said spouts to the arms aand b, said spouts may be held to the rearof the short axles, instead of forward thereof, as shown.

In the rear end portion of each of the innor arms a and b, is aperforation H through which may be inserted a bolt for the attachment ofa shoe or runner drill (not shown). On the bar A is a lug 77. havingtherein an aperture to which is connected one end of a chain H, theother end being designed to be attached to a lever on the frame, for thepurpose of raising the attachment from the ground.

The operation will be readily understood. The disks or colters D, D,together with the cutters G, open the drills, into which the grain dropsfrom the spouts F, F.

Having described this invention, what I claim as new, and desire tosecure by Letters Patent is:

1. The herein described seed drill attachment for grain drills, saidattachment comprising the drag bar formed in two parts,

spread at their front and rear portions, said rear portions being eachcurved laterally and downwardly, and bifurcated, the short axlesjournaled in said bifurcations, the disks or colters carried by saidaxles, and the grain spouts adjacent to said disks or colters,substantially as specified.

2. The combination with the drag bar A, formed in two parts securedtogether at their intermediate portions, and curved laterally anddownwardly at their rear portions to form the arms B, B, each of saidarms being bifurcated, the short axles journaled in adjustable bracketscarried by said bifurcations, the concavo-convex disks or colterscarried by said axles, the grain spouts adjustably clipped to saidbifurcated portions, said spouts being turned rearwardly at their lowerends, and cutters secured to said spouts,substantially as specified.

In testimony whereofIaffix my signature in presence of two witnesses.

WARREN WEBSTER.
